[0023] Reference Figure 1-4 The automatic perforating device for biodegradable plastic film includes a base plate 1 fixed to the ground for stability. A base 2 is mounted horizontally on the base plate 1, and a support column 3 is mounted on the base 2 to provide stable support for the support column 3. A punching device body 4 is mounted horizontally on the top of the support column 3, and the punching device body 4 is equipped with several punches for punching holes. A rectangular frame 5 is fixed to the side of the support column 3, and a clamping roller mechanism is provided on both sides of the rectangular frame 5.

[0024] For the above example, those skilled in the art should know that when implementing the above technical solution, the punching device body 4 is an existing punching device. The working principle of the punching device body 4 is to press the heated punch directly into the plastic material, and use the heat to soften the plastic, thereby forming a hole with smooth edges. The several punches of the punching device body 4 can be lifted and lowered by pneumatic means, or by a piston mechanism.

[0025] For the above examples, those skilled in the art should know that when implementing the above technical solution, it is not limited to setting up the punching device body 4, and existing laser punching equipment or existing ultrasonic punching equipment can also be set.

[0026] For the above example, those skilled in the art should know that when implementing the above technical solution, the number of punching holes corresponding to the punching device body 4 can be set according to needs.

[0027] As a technical optimization solution of the present invention, a drive motor 6 is provided on the upper side of the base plate 1 for driving the horizontal movement of the base 2. A rack 7 is fixed horizontally and laterally to the upper side of the base plate 1. A gear that meshes with the rack 7 is coaxially fixed to the drive motor 6. The drive motor 6 can accurately drive the gear in forward and reverse rotation. The meshing effect of the gear and rack 7 can control the left and right movement of the base 2 by starting the drive motor 6.

[0028] As a technical optimization solution of the present invention, a support frame 8 is fixed to the side of the base plate 1, and two oil cylinders 9 are installed on the support frame 8. The two oil cylinders 9 are arranged horizontally, and the telescopic ends of the two oil cylinders 9 are both facing one end. The sides of the punching device body 4 and the base 2 are respectively provided with slots that match the telescopic ends of the two oil cylinders 9. The telescopic ends of the two oil cylinders 9 are respectively inserted into the slots of the punching device body 4 and the base 2, which can achieve stable positioning and fixation of the punching device body 4 and the base 2, ensuring the normal operation of subsequent punching operations.

[0029] As a technical optimization solution of the present invention, a rectangular plate 10 is detachably fixed in the middle of the rectangular frame 5. A number of circular holes are provided on the rectangular plate 10. The number of circular holes are used to correspond to the number of punches of the punching equipment body 4. The rectangular plate 10 serves as a bottom mold, and the number of circular holes thereon can cooperate with the punching equipment body 4 to perform punching operations.

[0030] As a technical optimization solution of the present invention, a frame 11 fixed to the side of the support column 3 is provided at the bottom of the rectangular frame 5, and a box body 12 is provided on the frame 11. The box body 12 can collect the waste generated during the punching process and can be pulled out for cleaning.

[0031] As a technical optimization solution of the present invention, the clamping roller mechanism includes a mounting frame 13 fixedly mounted on the side of the rectangular frame 5. A first guide roller 14 is rotatably mounted at the bottom of the mounting frame 13. An electric telescopic rod 15 is vertically fixed to each end of the mounting frame 13. The telescopic ends of the two electric telescopic rods 15 face downward and are fixed with sliders 16. Both sliders 16 are slidably connected to the mounting frame 13. A second guide roller 17 is rotatably mounted between the two sliders 16. The surfaces of the first guide roller 14 and the second guide roller 17 are provided with a rubber layer. The second guide roller 17 can be controlled to move downward, thereby clamping the plastic film through the first guide roller 14 and the second guide roller 17.

[0032] As a technical optimization solution of the present invention, a feed roller 18 and a take-up roller 19 are rotatably mounted on each end of the base plate 1. The feed rollers 18 and take-up rollers 19 are arranged parallel to each other, with the support column 3 positioned between them. The feed rollers 18 and take-up rollers 19 are also aligned parallel to the first guide roller 14 and the second guide roller 17. The feed roller 18 takes up the raw plastic film, while the take-up roller 19 takes up the finished plastic film after the perforation operation.

[0033] For the above example, those skilled in the art should know that when implementing the above technical solution, the raw material roller 18 and the winding roller 19 are both rotatably set on the base plate 1 through the bracket, and the side of the bracket corresponding to the winding roller 19 is installed with a servo motor for driving the winding roller 19 to rotate, which can accurately control the winding roller 19 to rotate the plastic film.

[0034] In the present invention, the working principle of the device is as follows:

[0035] During the normal and continuous automatic punching operation of the degradable plastic film, the degradable plastic film is pulled out from the raw material roller 18 and passes through two clamping roller mechanisms in turn, that is, between the first guide roller 14 and the second guide roller 17 corresponding to the clamping roller mechanism. At this time, there is a gap between the first guide roller 14 and the second guide roller 17 for its passage. When passing through the bottom of the punching equipment body 4, the punching operation can be performed. The rectangular plate 10 serves as the bottom mold, and the several circular holes thereon cooperate with the punching equipment body 4 for the punching operation, that is, the several punches of the punching equipment body 4 are directly pressed into the plastic material and correspond to the circular holes of the rectangular plate 10, thereby forming holes. The box body 12 at the bottom of the rectangular frame 5 can collect the waste generated during the punching process.

[0036] When a roll of raw material roll 18 is used up and a new raw material roll 18 is installed and the film feeding operation needs to be performed again, the base 2 can be started and controlled to move horizontally close to the side of the raw material roll 18, and then one end of the plastic film is pulled out from the new raw material roll 18 and set in the nearest clamping roller mechanism, and the end of the plastic film is clamped by the first guide roller 14 and the second guide roller 17 of the clamping roller mechanism, that is, the corresponding two electric telescopic rods 15 are started to drive the two sliders 16 to move downward, that is, drive the second guide roller 17 to move downward, and finally the first guide roller 14 and the second guide roller 17 clamp the end of the plastic film. Since the surfaces of the first guide roller 14 and the second guide roller 17 are provided with a rubber layer, they can be compressed and deformed when in contact, that is, an effective and stable downward clamping operation can be performed. After that, the base 2 is controlled to move again and move to the side of the winding roller 19. At this time, a new winding roller 19 has been replaced. After the base 2 approaches the winding roller 19, the clamped plastic film end is loosened and pulled out, and it is pasted on the winding roller 19. After that, the winding roller 19 can be started to rotate. Before that, the base 2 can be started again and reset. During the reset process, the base 2 moves intermittently, and the punching device body 4 can perform the punching operation to ensure that the section of plastic film can be punched. After resetting, the above-mentioned normal punching operation can be performed.

[0037] During the reset process, the base 2 moves intermittently, and when the punching device body 4 performs the punching operation, each time a hole is punched, the first guide roller 14 and the second guide roller 17 corresponding to the two ends clamp the plastic film on both sides, effectively ensuring that the punching device body 4 in the middle can perform a stable punching operation. After the base 2 is reset, the two oil cylinders 9 on the support frame 8 can be started, and the telescopic ends of the two oil cylinders 9 are respectively inserted into the slots of the punching device body 4 and the base 2, so that the punching device body 4 and the base 2 can be stably positioned and fixed, ensuring the normal operation of the subsequent punching operation.

[0038] This device does not require manual film feeding operation, that is, there is no need for staff to take out the plastic film and then send it to the punching machine for punching. The overall work efficiency is high, it is not easy to make mistakes, and the waste of plastic film raw materials is effectively avoided.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
